Starting in 1995, many human rights organizations have reported on contemporary practice, especially in the context of the Second Sudanese civil war. According to reports of Human Rights Watch and others, during the war the government of Sudan was involved in backing and arming numerous slave-taking militias in the country as part of its war against the SPLA.[1] It also found the government failed to enforce Sudanese laws against kidnapping, assault and forced labor, or to help victims' families locate their children.[1])

Another report (by the International Eminent Persons Group) found both the government-backed militias and the rebels (led by the SPLA) guilty of abducting civilians, though the abducting civilians by pro-government militias was "of particular concern" and "in a significant number of cases", led to slavery "under the definition of slavery in the International Slavery Convention of 1926.[2][3] The Sudanese government maintained that the slavery is the product of inter-tribal warfare, over which it had no control.[1]

According to the Rift Valley Institute, slave raiding and abduction "effectively ceased" in 2002, although an "unknown number" of slaves remain in captivity.[4][5]

Prisoners of war were a regular occurrence in the ancient Nile Valley and Africa. During times of conquest and after winning battles, the ancient Nubians took Egyptian slaves.[6] In turn, the ancient Egyptians took slaves after winning battles with the Libyans, Canaanites, and Nubians.[7]

Soon after the Arab conquest of Egypt, the Arabs attempted to conquer the kingdoms of Christian Nubia on multiple occasions, but utilizing strategic guerilla-like warfare, the significantly smaller Christian Nubia defeated the larger Arab forces. Eventually, given their unsuccessful efforts, the Arabs signed the 600-year treaty of baqt with the Christian Nubian kingdom of Makuria. As a part of the treaty, the Nubians, already involved in the burgeoning East African slave trade, agreed to trade 360 slaves annually to their northern neighbors in exchange for spices and grains.

After the Nubian kingdoms' fall in 1504, the Ottomans conquered most of Nubia, while the Funj conquered much of modern day Sudan from Darfur to Khartoum ; the Funj began to use slaves in the army in the reign of Badi III (r. 1692-1711).[8] Later, Egyptian slavers began raiding modern South Sudan. In particular, the ruler Muhammad Ali of Egypt attempted to build up an army of Southern Sudanese slaves with the aid of the Nubian slavers. Attempts to ban slavery were later attempted by colonial British authorities in 1899, after they conquered the region.

According to British explorer (and abolitionist) Samuel Baker, who visited Khartoum in 1862 six decades after the British had declared slave trade illegal, slave trade was the industry "that kept Khartoum going as a bustling town".[9] Baker described the practice of slave raiding of African villages to the south by slavers in Khartoum: An armed group would sail up the Nile, find a convenient African village, surround it during night and attack just before dawn, burning huts and shooting. Women and young adults would be captured and bound with "forked poles on their shoulders", hand tied to the pole in front, children bound to their mothers. To render "the village so poor that surviving inhabitants would be force to collaborate with slavers on their next excursion against neighboring villages," the village would be looted of cattle, grain, ivory, with everything else destroyed.[9]

In the late 19th century, two thirds of Khartoum's population were slaves, according to historian Douglas H. Johnson.[10]

The "current wave" of slavery in Sudan reportedly began in 1983 with the Second Sudanese Civil War between the North and South. It involved large numbers of "African" Sudanese, "primarily the Dinka, Nuer and Nuba of central Sudan," being captured and sold "(or exploited in other ways)" by Northern Sudanese "Arabs".[11][12] The problem of slavery reportedly became worse after the National Islamic Front-backed military government took power in 1989, the Khartoum government declared jihad against non-Muslim opposition in the south.[13] The Baggara were also given freedom "to kill these groups, loot their wealth, capture slaves, expel the rest from the territories, and forcefully settle their lands."[14]

requires initiating hostilities for religious purposes ... It is true that the [NIF] regime has not enacted a law to realize slavery in Sudan. But the traditional concept of jihad does allow slavery as a by-product [of jihad].[15]

Human Rights Watch and others have described the contemporary form of slavery in Sudan as mainly the work of the armed, government-backed militia of the Baggara tribes who raid civilians—primarily of the Dinka ethnic group from the southern region of Bahr El Ghazal. The Baggara captured children and women who were taken to western Sudan and elsewhere. They were "forced to work for free in homes and in fields, punished when they refuse, and abused physically and sometimes sexually". The government of Sudan "arm[ed] and sanction[ed] the practice of slavery by this tribal militia", known as muraheleen, as a low cost way of weakening its enemy in the Second Sudanese Civil War, the rebel Sudan People's Liberation Movement/Army (SPLM/A), which was thought to have a base of support among the Dinka tribe of southern Sudan.[1]

According to a 2002 report issued by the International Eminent Persons Group, (acting with the encouragement of the US State Department) both the government-backed militias and the rebels (led by the SPLA) have been found guilty of abducting civilians, but "of particular concern" were incidents that occurred "in conjunction with attacks by pro-government militias known as murahaleen on villages in SPLA-controlled areas near the boundary between northern and southern Sudan." The Group concluded that "in a significant number of cases", abduction is the first stage in "a pattern of abuse that falls under the definition of slavery in the International Slavery Convention of 1926 and the Supplementary Convention of 1956."[2]

Estimates of abductions during the war range from 14,000 to 200,000.[19] One estimate (by Jok Madut Jok) is of 10-15,000 slaves in Sudan "at any one time", the number remaining roughly constant as individual slaves come and go—as captives escape, have their freedom bought or are released as unfit for labor, more are captured.[20] Until 1999, the number of slaves kept by slave taker retains after the distribution of the human war booty was usually "three to six and rarely exceeded ten per slave raider". Although modern slave trading never approached the scale of nineteenth-century Nilotic slavery, some Baggara "operated as brokers to convert the war captives into slaves", selling slaves "at scattered points throughout Western Sudan", and "as far north as Kharoum". Illegal and highly unpopular internationally, the trade is done "discreetly", and kept to a "minimal level" so that "evidence for it is very difficult to obtain." "Slave owners simply deny that Southern children working for them are slaves." [21]

According to a January 25, 1999, report in CBS news, slaves have been sold for $50 apiece.[22]

What's Sudanese slavery like? One 11-year-old Christian boy told me about his first days in captivity: "I was told to be a Muslim several times, and I refused, which is why they cut off my finger." Twelve-year-old Alokor Ngor Deng was taken as a slave in 1993. She has not seen her mother since the slave raiders sold the two to different masters. Thirteen-year-old Akon was seized by Sudanese military while in her village five years ago. She was gang-raped by six government soldiers, and witnessed seven executions before being sold to a Sudanese Arab.

Many freed slaves bore signs of beatings, burnings and other tortures. More than three-quarters of formerly enslaved women and girls reported rapes.

While nongovernmental organizations argue over how to end slavery, few deny the existence of the practice. ...[E]stimates of the number of blacks now enslaved in Sudan vary from tens of thousands to hundreds of thousands (not counting those sold as forced labour in Libya)...

The Sudanese government has never admitted to the existence of "slavery" within their borders,[24][25] but in 1999, under international pressure, it established the Committee to Eradicate the Abduction of Women and Children (CEAWC). 4,000 "abducted" southerners were returned to South Sudan through this program before it was shut down in 2010.[26]

End of trade

According to the Rift Valley Institute, slave-raiding, "abduction … effectively ceased" in 2002. "A significant number" of slaves were repatriated after 2005 the Comprehensive Peace Agreement of 2005, but "an unknown number" remain in captivity.[4] The Institute created a "Sudan Abductee Database" containing "the names of over 11,000 people who were abducted in 20 years of slave-raiding" in Northern Bahr el-Ghazal state in southern Sudan, from 1983 to 2002.[4][5] The January 2005 "North/South Comprehensive Peace Agreement (CPA)" peace treaty that ended the Sudanese civil war[27] put an end to the slave raids, according to Christian Solidarity International, but did not provide a "way home for those already enslaved."[28] The last Human Rights Watch "Backgrounder on Slavery in Sudan" was updated March 2002.[1]

Efforts to "redeem" or to buy the freedom of slaves in Sudan are controversial.[1] Beginning in 1995, Christian Solidarity International began "redeeming" slaves through an underground network of traders set up through local peace agreements between Arab and southern chiefs. The group claims to have freed over 80,000 people in this manner since that time.[29] Several other charities eventually followed suit.

In 1999, UNICEF called the practice of redeeming slaves 'intolerable', arguing that these charities are implicitly accepting that human beings can be bought and sold.[30]

UNICEF also said that buying slaves from slave-traders gives them cash to purchase arms and ammunition. But Christian Solidarity said they purchase slaves in Sudanese pounds, not dollars, which could be used to purchase arms.[30]

As of 2015, Christian Solidarity International states that it continues redeeming slaves. On its website,[29] the group states that it employs safeguards against fraud, and that allegations of fraud "remain today unsubstantiated".

^According to researcher Jok Madut Jok, extensive accounts of slave raiding since 1995 can be found in US magazines and newspapers: The New Yorker, The Washington Post, The Washington Times, The New York Times, The Los Angeles Times, The Boston Globe, as well as The South African Mail and Guardian, and a number of European and Canadian magazines and newspapers. "Many of them have also tried to expose the role of the government in slave taking." [18]
In Sudan itself "systematic and instrumental journalistic writing" on slavery has come from Bona Malwal (a Sudanese journalist and former government minister), who pioneered the campaign to expose the practice in the 1980s as editor of the Sudan Times, [18]

^"Slavery and Slave Redemption in the Sudan". hrw.org. Human Rights Watch. March 2002. Retrieved 26 October 2015. The government of Sudan has stonewalled on the issue of slavery, claiming it was a matter of rival tribes engaging in hostage taking, over which it had little control. That is simply untrue, as myriad reports coming out of southern Sudan have made abundantly clear.
